Linux has strong exhortations not to use the function.
NAME
getpass - get a password
SYNOPSIS
#include <unistd.h>
char *getpass( const char * prompt );
DESCRIPTION
This function is obsolete. Do not use it.
The getpass() function opens /dev/tty (the controlling terminal
of the
process), outputs the string prompt, turns off echoing, reads
one line
(the "password"), restores the terminal state and closes
/dev/tty
again.

Present in SUSv2, but marked LEGACY. Removed in POSIX.1-2001.
Should we remove it? Replace it?
I'm open to suggestions? I'm not aware of any 'easy' functions to do
the same thing. Could write a whole tonne of sick code which uses the
tcgetattr/tcsetattr() apis to turn off echoing on stdin, but getpass
was simpler. Maybe gnulib has something we can use ?
